Specification of Letters Patent.

Application filed January 5, 1912. Serial No. 669,604.

To all whom it may concern:

Be it known that I ALFRED BAGNALL, a tates, and a resident of the cityand county of Philadelphia and 'State of Pennsylvania, have invented anImprovement in Fixtures for Supplying Paper, &c., from Rolls, of whichthe following is a specification.

More particularly this invention relates to fixtures in which a roll ofpaper or other material is supported on a rotary roller or mandrel, sothat the paper may be drawn out for use.

While the fixture is articularly designed for use with rolls of papertoweling, it may also be used with other materials.

It is the principal object of my invention to prevent the removal of aroll from the mandrel after it has been laced in the fixture, thusmaking impossi le thefts of new or partially used rolls bytakingthemi'rom the fixture. This object I accomplish by means of anextensible mandrel with suitable locking devices to lock the mandrel inextended position against removal from the frame of the fixture afterthe roll has been applied, such locking devices being so arranged uponthe mandrel as to be inclosed by the roll and thus rendered inaccesibleto manipulation until the roll is unwound. The locking device may thenbe operated to contract the mandrel and remove it from the frame so thata fresh roll may be applied.

The invention also relates to various teas tures of construction andcombinations of parts which are fullyset forth hereinafter.

Figures 1 and 2 are respectively a longitudinal vertical section and atransverse vertical section taken, the one on line A-A of Fig. 2, andthe other on line BB of Fig. 1; Fig. 3 is a plan view on an enlargedscale of one end of .the mandrel showing the spring for controlling thespring-knob; Fig. 4 is a transverse sectionon the line GC of Fig. 3;Fig. 5 is a similar View supposing the spring-knob to have beenpushed into the extent indicated by the section line D-D of Fig. 3; Fig. 6 is aperspective view of the mandrel; and Fig. 7 is a similar view of theadjustable bearing for the mandrel spring.

a is a tubular mandrel upon which the roll of paper I) is supported. Thepaper roll usually has a tubular core I) and is slipped upon the mandrelwhen the latter is removed from the supporting frame. The mandrel a isprovided at one end with a fixed knob c and at the other end with aspring-knob (Z.

The shanks h h of these knobs are inserted in slots 6 in the ends f ofthe housing 9, and are provided wit enlargements e c which form journalsfittin bearings e c in the ends I. The shanks h h project through theendsf f so that the mandrel may be rotated to unroll the paper. As shownthehousing is provided at the back with flanges g g for attachment tothe wall. The shank it of the knob (Z is free to move longitudinally inthe mandrel and is pressed outward by a spring 9' in the mandrel, thetension of which spring may be regulated by a sliding bearing isadjusted by a screw m extending through the shank of the fixed knob s. Apin a extending through a slot 11. in the bearing It prevents rotationof the bearing and insures its longitudinal movement when it is adjustedby the screw m. ()n the end of the mandrel which carries the movableknob is a spring 0 having a slot 7), through which extends a screw orpin carried by the shank of themovable knob (Z and extending through aslot 0 in the mandrel. The slot 79 extends longitudinally and isprovided at its outer end with an enlarged aperture and terminates atits inner end in a sharp angle p. The pin g which extends through theslot 27 has below its head an enlargement g which loosely fits theenlarged aperture in the outer end of the spring but cannot pass throughthe length of the slot 79. It follows that when the knob (Z and itsshank h are projected, as shown in Figs. 1, 8 and i, the enlargement gof the pin Q will fit in the enlarged aperture of the spring and theknob cl will be held in projected position with its journal 6 in thebearing e of the side of the housing. This is the position occupied bythe knob (l when a roll of paper is mounted on the mandrel, and whilethe parts are in this position the mandrel cannot be removed from thehous-. ing, since the enlargements e a, forming the journals, areretained in the bearings c c and prevent the shanks of the knobs frombeing withdrawn through the slots.

In order to press in the knob d and remove the mandrel it is necessaryto depress the spring 0 as the enlargement in the slot p which engagesthe enlarged portion q of the pin 9 acts as a locking device, which canbe unlocked only by themanual depression able longitudinally,

of the spring to freethe part 9 from the enlargement of-the slot.

The spring cannot be manipulated while the roll of paper is on themandrel, and, consequently a roll cannot be removed until it is used orunwound. When the mandrel is empty the spring 0 is depressed and theknob d is pushed in and turned to move the pin q. into the angular andthe mandrel may be removed and a new roll-placed in it. The mandrel isthen re placedxin the slots 6 e and the handled is turned to releasethepin 9 fromthe angular portion. 9 of the slot p. The knob al is then" proected and the mandrel is locked in position as before and cannotbe againremoved until the new roll is used or unrolled. Thus ,theft bythe-iremoval of new or partially used rolls is effectively prevented.

I do not meanto confine myself to the details of construction shownwhich may be variedwithout departing from the invention.

What I claim is as follows:

etsiprovidedwith slots, a mandrel provided onz its ends with knobshaving shanks adapteditopassthrough the slots-in theframe andprovidedwith journals adapted to fit the,

provided with journals adapted to fit the bearing-sockets, one of saidknobs being movand locking devices carried bythe mandrel to lock saidknob in extended and retracted position.

3. In a device for-the purposes stated, the combination of a framehaving bearing-sockets provided with slots,,a mandrel provided on itsends with knobs having shanks adapted to pass through the slots of theframe andprovided with journals adapted to fit the bearing-sockets, oneof said knobs being movable longitudinally, and locking devicescarriedbyithe mandrel to lock said knob in ex-. tended and retractedposition, said locking devices consisting of a :spring 0 carried by themandrel and provided with a slot p havportion p of the slot p.-This-locks the knob din retracted position- 1.
